I decided to do a prologue to Romeo and Juliet, explaining why the Capulet's and the Montague's hate each other.
Setting:Verona, 20 years prior to Romeo and Juliet

Montague: My good friend Capulet,what revelries
shall we have today,For it has been a
fortnight since we have gone out.

Capulet: That I know not. There is to be a
Queen Mab festival down yonder grove.
It has been said that many fine young maidens
wander these fairs.

Montague: What merriment or troubles shall find us
there, I know not.

(walk to festival)

Capulet:Dost thou see that fair maiden o'er yonder?
Zounds, dost her hair not shine like gold, crafted
by the angels and eyes of a crashing oceans?
By god, Her beauty would incite jealously in Venus.

Montague: Aye friend, she is a treasure indeed.
Stand back, I will make myself known to her.

Capulet: Nay! She is mine! I spotted her before
thee, therefore she is mine!

(Montague sighs)

Montague: Aye, ‘tis true in all fairness. Go and woo.

(Capulet goes and talks to girl)

Montague: yes, go. Woo her if thou thinketh it will
do thee any good. But know, dear Capulet,
I shall win her and she shall be mine. (turns to peasant)
Good sir! Sir, who is that fine young maiden over yonder?

Man: lo, that is Caroline Monroe, she
is a beauteous one, is she not?

Montague: Aye.

Man: She is but 15. Dost thou wish me to
introduce thee unto her?

Montague: Aye, do!

(Walk to girl)

Caroline: Hello father, who is this?

Monroe: Caroline, this is Sir Montague,
he has expressed great interest in thee.

Caroline: Oh father, surely thou bluffs, for you are
always all politeness.

Montague: Oh, no my lady,
thou father has lied not. Thou art more radiant
than one-thousand suns, And thine eyes shine with a heavenly shine.

Caroline: thou art truly all politeness. If my
father is willing, it would pleasure me
To have thee at my dwelling for dinner. Father?

Monroe: It would be a great honor to have thee.

Montague: Aye, I shall come. Thank you, good sir.And thou too,
fine lady.

( Montague walks away and enters Capulet, who has seen and heard everything that happened)

Capulet: Ye scurvy knave! Miserable dog!
Thou hath sworn to me! Thou hath swore to me!

Montague: I know not what thou are talking of.

Capulet: Thou hath swore thou shalt leave Caroline for
me, for I hath found her first. But thou hast lied
and taken her from my fingers.

Montague: Capulet, calm thyself.
Thou knowest not the truth.

Capulet: I care not!
You took her from me. Thee, my comrade since birth,
hast betrayed me! Have thou no shame?

Montague: I betray? I betray?
Lo- a lie has been spoken.
‘Tis not my fault she fancies I
more than thee! That my friend be not my
problem but thine own.

Capulet: Not even an apology thou shalt
give me? Wretched man. You have won this maiden,
but thou hast lost thy friend. From this day forward,
The Capulet’s and the Montague’s shall
be sworn adversaries.

Montague: ‘Tis no loss to me!
From now until the end of time, I want
no part in the Capulets.
Good day, Capulet, and be on thine way.

Some lines are in iambic pentameter and some are not; i think you could defiantly try to make them all in true Shakespearian fashion.
Other than that this is really good. I feel like it is totally logical and something that would happen. You keep me wondering; is Lady Capulet really Caroline and that is what still drives the haate between the two families? Maybe you should just throw in a tiny note at the end like that. I found no errors in your gammer as well, and it flows very well.
